Product Introduction:
The KA2000 inertial-grade accelerometer produced by KACISE has long-term repeatability and excellent reliability. It is mainly used in core navigation components in the aerospace field, while-drilling measurement in oil and gas exploration and other scenarios.
The integral electronics develops an acceleration-proportional output current providing both static and dynamic acceleration measurement. By use of customer supplied output load resistor, appropriately scaled for the acceleration range of the application, the output current can be converted into a voltage.
The KA2000 also includes a current-output, internal temperature sensor. By applying temperature-compensating algorithms, bias, scale factor, and axis misalignment performance are dramatically improved.
